Third-Quarter and Year-to-Date 2025 Highlights by Business Segment

Sterigenics

Sterigenics delivered solid results for the third-quarter 2025, with net revenues up 9.8% to $193 million, or 8.4% on a constant currency basis, compared to the third-quarter of 2024. Third-quarter 2025 segment income was $107 million, a double-digit increase of 11.6%.

Segment income increased 8.7% to $303 million.

Revenue growth for the quarter was driven by favorable volume and mix, pricing and changes in foreign currency exchange rates. Segment income and segment income margin increased for the quarter due to favorable volume and mix, as well as pricing, partially offset by inflation.

Nordion

Nordion net revenues increased 22.4% to $63 million, or 23.6% on a constant currency basis, compared to the third-quarter of 2024. Third-quarter 2025 segment income increased 19.9% to $38 million.

Segment income increased 19.7% to $79 million.

Revenue growth for the quarter was driven by favorable volume and mix, as well as pricing, partially offset by unfavorable changes in foreign currency exchange rates. The increase in segment income was attributable to growth in volume and mix and benefits from customer pricing. Segment income margin decreased as a result of product mix.

Nelson Labs

Nelson Labs net revenues decreased 5.0% to $56 million, or 6.4% on a constant currency basis, compared to the third-quarter of 2024. Nelson Labs third-quarter 2025 segment income increased 1.9% to $19 million.

Segment income increased 7.4% to $55 million.

Change in revenues for the quarter were driven by favorable pricing, changes in foreign currency exchange rates, and improvement in core lab testing services, offset by a decline in expert advisory services revenues. Segment income and segment income margin increased for the quarter as a result of volume and mix improvements, lab optimization and favorable pricing.

Balance Sheet and Liquidity

As of September 30, 2025, Sotera Health had $2.2 billion of total debt and $299 million in unrestricted cash and cash equivalents, compared to $2.3 billion in total debt and $277 million of unrestricted cash and cash equivalents as of December 31, 2024.

As of September 30, 2025, the Company did not have any borrowings on its revolving credit facility.

In the third-quarter of 2025, the Company achieved a contractual net leverage target, triggering a 25 basis point reduction in the interest rate on its First Lien Term Loan facility. Additionally, on September 17, 2025 the Company amended its First Lien Term Loan facility, which reduced the interest rate spread over SOFR from 300 basis points to 250 basis points, and concurrently repaid $75 million of the facility.

Full-Year 2025 Outlook

Today, Sotera Health is updating its 2025 outlook:

The Company does not provide a reconciliation for non-GAAP financial measures on a forward-looking basis where it is unable to provide a meaningful or accurate calculation or estimation of reconciling items without unreasonable effort. The Company cannot reconcile its expected Adjusted EBITDA, Tax Rate Applicable to Net Income, Adjusted Net Income and Adjusted EPS without unreasonable effort because certain items that impact net income, earnings per share and other reconciling metrics are out of the Company’s control and/or cannot be reasonably predicted at this time, including uncertainties caused by changes to the regulatory landscape, restructuring items and certain fair value measurements, all of which are potential adjustments for future earnings.

The outlook provided above contains a number of assumptions, including, among others, the Company’s current expectations regarding supply chain continuity, particularly for the supply of EO and Cobalt-60 (“Co-60”), and the impact of inflationary trends including their impact on energy prices and the supply of labor. Our outlook is based on current plans and expectations and is subject to several known and unknown risks and uncertainties, including those set forth below under “Cautionary Note Regarding Forward-Looking Statements.”

Non-GAAP and Financial Measures

To supplement our consolidated financial statements presented in accordance with GAAP, we consider Adjusted EBITDA, Adjusted EBITDA margin, Adjusted Net Income, Adjusted EPS, Net Debt and Net Leverage Ratio and constant currency, financial measures that are not based on any standardized methodology prescribed by GAAP.

We define Adjusted Net Income as net income (loss) before amortization and certain other adjustments that we do not consider in our evaluation of our ongoing operating performance from period to period.

We define Adjusted EBITDA as Adjusted Net Income before interest expense, depreciation (including depreciation of Co-60 used in our operations) and income tax provision applicable to Adjusted Net Income.

Adjusted EBITDA margin is equal to Adjusted EBITDA divided by net revenues.

We define Adjusted EPS as Adjusted Net Income divided by the weighted average number of diluted shares outstanding.

Our Net Debt is equal to our total debt net of unamortized debt issuance costs and debt discounts, less cash and cash equivalents.

Our Net Leverage Ratio is equal to Net Debt divided by Adjusted EBITDA.

Constant currency is a non-GAAP financial measure we use to assess performance excluding the impact of foreign currency exchange rate changes. We calculate constant currency net revenues by translating prior year net revenues in local currency at the average exchange rates applicable for the current period. The translated results are then used to determine year-over-year percentage increases or decreases. We generally refer to such amounts calculated on a constant currency basis as excluding the impact of foreign currency exchange rates. These results should be considered in addition to, not as a substitute for, results reported in accordance with GAAP. Results on a constant currency basis, as we present them, may not be comparable to similarly titled measures used by other companies and are not measures of performance presented in accordance with GAAP.

We use these non-GAAP financial measures as the principal measures of our operating performance. Management believes these measures allow management to more effectively evaluate our operating performance and compare the results of our operations from period to period without the impact of certain non-cash items and non-routine items that we do not expect to continue at the same level in the future and other items that are not core to our operations. We believe that these measures are useful to our investors because they provide a more complete understanding of the factors and trends affecting our business than could be obtained without these measures and their disclosure. In addition, we believe these measures will assist investors in making comparisons to our historical operating results and analyzing the underlying performance of our operations for the periods presented. Our management also uses these measurements in their financial analysis and operational decision-making and Adjusted EBITDA serves as the key metric for the attainment of our primary annual incentive program. These measures may be calculated differently from, and therefore may not be comparable to, a similarly titled measure used by other companies.
